Quarantines are like speed bumps, they are just trying to keep the rate of spread at a level that prevents overloading hospitals etc. There may be several quarantines etc put in place and lifted every few weeks in the same areas over the next 6-12 month to try and control the spread . People have to remember these quarantines do not mean you don't go to work, or that you cant go to the store etc. It just means they want you to limit travel locally and interaction with others as much as possible, they also shut down things that allow for large public gatherings like movies, sporting events, concerts, no weddings and funerals etc.....they also try to prevent people from different areas traveling to other areas. In Italy the biggest problem they had were thousands of people self evacuating the hard hit Lombardy region for other parts of Italy, this is exactly what they do not want.
I suspect we start to see widespread school/University closures across the country, lots of canceled concerts, sporting events happening with no crowds etc...
Washington has reported 2 more deaths but more worrisome is that these two were at two different nursing homes and they now have positive cases of Corona in at least 10 different nursing homes....
